Nitrate occurs naturally in surface and groundwater at concentrations up to 1–2 $mg/L$and is not harmful at these levels. The safe drinking water standard for nitrate is 10$mg/L$.

Step by step answer: EPA has set an enforceable standard called a greatest toxin level in water for nitrates at 10 sections for each million ($ppm$) (10$mg/L$) and for nitrites at 1 ppm (1$mg/L$) EPA accepts that introduction underneath this level isn't required to cause critical medical conditions.
